Split master passwords into M-of-N threshold shares with GF(256) math.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Input the private key, password, or master recovery phrase.
Choose total shares (N) and required threshold (K) to reconstruct.
Distribute generated shares securely among trusted parties.
SSS provides information-theoretic security. Any group with fewer than the threshold K shares possesses zero mathematical knowledge about the original secret.
Zero-egress companion tools in the Security & Network suite
Audit CSP, HSTS, X-Frame-Options, and security headers with OWASP grading (A+ to F).
Measure cryptographic randomness, Shannon entropy (0-8 bits/byte), Chi-square test, and byte distributions.
Generate secure RFC 6238 Base32 TOTP secret keys and standard otpauth:// URIs for Google Authenticator.
Construct and validate HTTP CSP headers and meta tags.
